SAFETY DEVICE FOR INFLAMMABLE-MATEBIAL CONTAINERS.

vSpecification of Letters Patent.

Application filed April 30, 1914. Serial No. 835,476.

To all whom it may concern:

Be it known that I, VICTOR .GAUMER, a citizen of the French Republic,and resident of Paris, France, have invented certain new and usefulImprovements in Safety Devices for Inflammable-Material Containers, ofwhich the following is a specification.

The present invention relates to a safety device disposed on the inletand outlet parts of devices containing inflammable liquids or gases, forinstance: cans, lamps, dishes, tanks, carbureters and the like, and hasfor its object to prevent explosions. Said device stops any flame,preventing same from flowing into or out of said devices. With thisobject in view a body formed of a plurality of narrow channels isprovided, some of said superposed narrow channels being undulated, theothers straight, in, such a manner that the liquid or gas may freelyflow while any flame is prevented from passing. The principle ofprotecting such devices against explosions consists in separat ing aspace containing an explosive fluid from another space in which is aflame, by means of an interposed arrangement of elements having alinedapertures in such a manner that the fluid may freely flow from one spaceto the other, while a flame is prevented from passing to another, thegas being cooled at the same time.

The only protecting means known until now consists in wire gauze andisbased on the principle of the miners lamp. However the results obtainedhave not been satisfactory; they are irregular and not positive. Thesimple wire gauze does not fully meet the requirements of a safetydevice because it is always possible to make a flame pass through a wiregauze whatever may be the fineness of its mesh. In effect such wiregauze is very thin so that it does not positively. stop a flame norsufliciently cool the burning gas. Moreover owing to the weakness of thewire gauze, the meshes are becoming wider when exposed to shocks or tooxidation and the protective value of same is markedly decreased.

In order to provide a satisfactory device having a positive protectingpower, the

' principle of the wire gauze may be maintained but the latter should betransformed as follows: Increasing the thickness of same soas to providea positive impedi-- ment for the passage of the flame between bothspaces. Increasing the rigidity of gases, owing to the mass of metal.Increasing the freedom of flow by providing clear and unobstructedpassages for the liquid or gas and thereby decreasing the amount offluid or gas liable to waste by being left in the container and assuringthe speed of flow of the latter part of the liquid. Providing parts ofsmall dimension decreasing the danger of displacement and .dislodgmentdue to vibrations because of the small weight and area of the vibratingparts, the period of vibratory oscillations being materially decreasedover the larger and heavier objects, this makes the device of greatvalue to automobiles. In order to obtain such conditions, the thicknessof the wire gauze is increased, the material forming the wire gauzebeing extended in a direction perpendicular to the plane of same, sothat instead of meshes adjacent channels are formed, and instead of aweak wire gauze athick and resistant block formed with rigid tubes isformed, the section of said tubes being constant and well defined.

The present invention consists in providing a thick strainer formed by aplurality of adjacent'tubes or ducts for separating the two .spaces, bysuperposing undulated elements and straight elements, plates or washers.

' The accompanying drawing shows an example of the device and applied toa vessel containing inflammable fluid.

Figure 1 is an'undulated metal washer.

Fig. 2 is a smooth metal washer. Figs. 3 and 4 are sections taken onlines AB'and CD, respectively, of "Figs. 1 and 2. Fig. 5 is an axialsection through the safety device. Fig. 6 is a lateral view ofsa'me.

The safety device is formed by a plurality of undulated and smoothelements in shape of washers, superposed and connected together by meansof lateral fastenings or transverse rods or the like.

The washer a Fig. 1 is provided with undulations 1) extending from theedge of the central filling or emptying duct 0 to the outer edge, sothat when a smooth washer such as e (Fig. 2) is placed on top of same,

ducts or passages are left between both washers. d are apertures throughwhich extend the connecting rods. The openings f and g in Fig. 2correspond to the openings .0 and al of the washer shown in Figs. 1

and 3. r U

The device shown in Figs. 5'and 6 is secured by any known means on themouth i of a vessel b. A plurality of undulated washers shown in Figs. 1and 3 and of smooth washers shown in Figs. 2 and 4: are alternatelydisposed on top of each other so that between every two'washers ductsare provided for the flowing liquid. Said washers are secured togetherby means of transverse rods Z andnm the threaded ends of which beingengaged by tightening nuts n and 0 for securing the rigidity of thewhole system. With this object in view a bottom plate 3) is provided atthe lower part of the device. The undulated and smooth elements, thecombination of which forms the present invention, may be of any desiredshape,round, oval, square, rectangular and. the like.

Having now fully described my said invention what I claim and desire tosecure by Letters Patent, is; Y

1. A'device for the purpose substantially as set forth comprising, aseries of superposed disks alternately smooth and undumenses latedhaving their centers open, said super posed open centered disks forminga duct for the flow of the material through the center of said series ofdisks, a closure for one end of said duct, fastening means for saiddisks to hold same in superposition.

2. A device for the purpose substantially as set forth comprising,acylindrical plug having radial passages through its walls, said plugcomposed of a series of flat disks, alternately smoothed faced andcorrugated faced,varra-nged in superposition, means for fastening saiddisks, in superposition and a closure for one end of said cylindricalplug.

3. A safety device of the class described, consisting of a series offlat disks, said disks having apertures in' their centers and boltreceiving holes between their edges and center apertures, said series ofdisks alternately smooth and corrugated faced forming radial passagesand a centr'al duct when in superposition, a closure for one end of saidduct, bolts in said bolt receiving holes for holding said disks and saidduct closure in position.

lln testimony whereof I have hereunto set my hand in presence of twowitnesses.
